Breaking the bomb blocks is difficult because there is not enough space above them to get a neutral bounce. It is best to break them by jumping from the top platform (inside the 3-tile-high space), as this provides a 2-frame window for the morph; in comparison, jumping from the platform below requires a frame-perfect morph. If Spring Ball is available, it can be used to increase the window by one frame.

Leaving with upward momentum is possible in three ways: 1) Most easily, with a momentum-conserving morph against the ceiling through the transition, 2) With a momentum-conserving turnaround through the transition, or 3) Jumping specifically with a extra run speed $5.2 or $5.3 and aiming down through the transition. For the first two methods, back into the corner at the start of runway.

The momentum-conserving turnaround has a 2-frame window for the jump, and either a 3-frame or 5-frame for the turnaround (with the last-frame jump giving the larger window for the turnaround); again the windows can be more narrow depending on what is required in the next room. The aim-down method requires specific positioning to ensure Samus barely clears the door ledge with a frame-perfect jump.

Dev note: This can be done with HiJump alone; it requires a precise spin jump and then a very precise horizontal spark at the top of the jump.

Wait 3 minutes for a global Geemer to waddle over, or shoot a Super 20 to 30 seconds after entering the room to knock it off the ceiling and save a lot of time. Damage down until Samus is one Geemer hit away from running out of energy, and set reserves to manual. Crouch jump at a very precise time and mid-air morph to contact the Geemer at the peak of the jump, pressing pause to be in the fade-out while getting hit and reaching 0 energy. Set reserves to auto, unpause, and hold left. While reserves are auto-refilling, Samus' i-frames will run out, allowing Samus to be hit by the Geemer again and be boosted high enough to reach the ledge. The screen will be black, which can be fixed by pausing and unpausing again.

Wait for a global Geemer to make the long trip along the map, or shoot a Super 20 to 30 seconds after entering the room to knock it off the ceiling and save a lot of time. Hold right against the bomb blocks, take damage from the Geemer, jump, aim-down, and shoot the Geemer shortly before landing. Samus should end up standing on the ground with the Geemer frozen on the wall with a 4-8 pixel gap between it and the ground (overlapping Samus' hitbox). Facing the bomb blocks and pressed against them, jump while holding down (but not crouched) and then hold forward (or forward and down) 5 frames later to break the aim-down pose. If successful, Samus will clip up through the ceiling. This can be attempted several times before the Geemer thaws.

For the first two methods, back into the corner to use the full runway; it helps to use an arm pump to advance a single pixel while running.

Freeze all three Choots to significantly increase the length of the runway and run across the entire room. Freeze each immediately after it jumps in order to be able to run onto and off of it without a problem.

Using an exact runway size of 7 tiles; use extremely precise, controlled springball bounces to cross the ocean. 7 tiles of runspeed can freely be achieved by requipping SpeedBooster after reaching the max normal run speed. Mockball down the submerged ramp and begin SpringBall bouncing either above the water, or under water using the platforms.

Dev note: Max extra run speed $3.3 with spin, or $3.4 with a quick aim-down. This would not be logically valid for gaining blue speed, so we have to be sure it can't be used that way.

Leaving with upward momentum is possible in three ways: 1) Most easily, with a momentum-conserving morph against the ceiling through the transition, 2) With a momentum-conserving turnaround through the transition, or 3) Jumping specifically with a extra run speed between $5.2 and $5.4 and aiming down through the transition. For the first two methods, avoid backing into the corner; instead press against it and turn around, to put Samus into a better position. For the third method, use only the part of the runway in front of the Power Bomb blocks, or about a tile less.

The momentum-conserving turnaround has a 2-frame window for the jump: if jumping on the second-to-last possible frame, then there is a 4-frame window for the turnaround, while if jumping on the last frame, there is a 5-frame window for turning around before the transition or it can be buffered through the transition (or the turnaround could not be performed at all, to maintain forward and upward momentum by simply aiming down).

Break the bomb block at the bottom right of the main shaft. Bring a Zeela down to the bottom of the room. Morph inside the tunnel, take a Zeela hit, then jump, aim down, and shoot to freeze the Zeela as it starts to move up and while Samus is close to landing. Jump and aim down to get on top of the Zeela. If the Zeela is precisely positioned exactly 12 pixels above the ground, you can press up to make Samus stand; Otherwise, if you have X-ray, then the Zeela should be frozen lower, and you can morph and unmorph and use X-ray to force Samus to stand up; in this case there is a 6-pixel window over which it works, with the Zeela being between 4 and 9 pixels above the ground. In either case, after standing up on top of the Zeela, jump and aim down to break the crumble block. Then, before the crumble respawns, morph and use Spring Ball (if available) to jump back up and into the tunnel; without Spring Ball, a quick mid-air morph also works but is more difficult.

Note that jumping directly against the wall to clip into it will put Samus into a forced crouch, unable to use X-Ray. Samus may either 1) perform a Crystal Flash to stand up, 2) use neutral knockback from a Reo to put Samus standing inside the wall, or 3) use the frozen Reo as a platform to run and clip into the wall. To manipulate the Reo into a suitable position, lure it to the left and crouch at the edge of the platform; jump as needed to bring it back on camera when it goes off; it should perform 4 big swoops down to the left, 2 small swoops (hitting the overhang above), then 5 more big swoops, after which it will enter a slow hover moving directly towards Samus. Freeze the Reo when its left side is approximately flush with the ledge, or up to about a tile to the right. After X-Ray climbing about 1.5 screens, the sound of the crumble blocks breaking is an indication that it is safe to end the climb, either by jumping up or by falling out to the right. Alternatively, there's no harm in continuing to climb, as the lack of door means it's impossible to climb beyond the destination.

Dev note: The Zeb moves 2 pixels per frame, and there are 3 positions where it can be frozen inside the wall using Ice beam alone, namely 2 pixels, 4 pixels, or 6 pixels deep inside the wall. For the method that uses the frozen Reo as a platform, only the 2-pixel-deep position will work; by moonwalking back inside the 2-tile space, it will work 100% reliably as long as the Zeb is frozen in that exact spot. For the method that jumps directly into the wall (with a Crystal Flash), either 2 or 4 pixels can work, or 6 with SpeedBooster; it will work more reliably the less deeply the Zeb is frozen inside the wall. Likewise, with the Reo knockback method either 2 or 4 pixels can work, though it is more reliable in the 2-pixel position; it helps to take the knockback a few pixels away from the wall, as it takes a few frames for the horizontal speed of the knockback to reach its maximum. The trick can work with Samus facing either toward or away from the wall when taking knockback; facing away makes it easier to quickly kill the Reo afterward to avoid taking a second hit.

Raise a Zeb to be just below the crumble blocks and blindly freeze it to set up an ice clip to reach the Power Bomb room exit door. Get a bug from the pipe to spawn facing left and freeze it while moving to the ledge below the Hopper room door. While crouched, a spazer or wave beam shot will shoot through the floor in front of Samus. Shoot then immediately jump so that the bug can be frozen at a pixel perfect height, which is higher than where it would typically be frozen (when not needing to preserve a flash suit). Once frozen, wait for the bug to thaw, then blindly follow it to the left without letting it go off camera, which would cause it to despawn. Refreeze it below the crumble blocks, perform a very precise ledge grab onto it, then jump through the crumble block to reach the door, all while carefully avoiding losing the flash suit.

Freeze the Reo when its left side is approximately flush with the ledge, or up to about a tile to the right. After X-Ray climbing a little over half a screen, it is possible to aim up and shoot the door (if it is blue) and listen for if it opens, to test if you are high enough to safely jump up. Alternatively, the sound of the crumble blocks breaking will indicate when Samus' feet are level with the bottom of the door.

Enter with G-Mode and use X-Ray to get stuck 9 pixels inside the door. X-Ray climb to a relatively specific height: after just one pixel of Samus' feet are visible while crouching facing left, perform between 20 and 22 more X-Ray stand-ups (any of these work). Use X-ray to face left, then run and jump to barely make it onto the ledge.

Get stuck 3 pixels inside the door, and X-ray climb to a precise height: after just one pixel of Samus' feet are visible while crouching facing left, perform exactly 7 more X-Ray stand-ups. Use X-ray to face left, then run and jump to barely make it onto the ledge.

Traverse the room while rolling on the thorns and avoiding the Samus Eaters. Roll from the first platform onto the thorns under the first set of Boyons. When just past the first Boyons, turn right and wait on the safe spot for a second to overload PLMs. Move right to touch the thorns and use that to damage boost leftwards onto the next thorns and roll into the third Samus Eater. Place a Power Bomb and then quickly unmorph and jump onto the block above and exit G-Mode before the Power Bomb explodes to break the wall. Note that if Samus is teleported into the Samus Eater when exiting G-Mode, then PLMs weren't properly overloaded before entering it. PLMs can be overloaded by waiting on their petals before entering them. Also note that there are much easier strats with more Energy or more Power Bombs.

Jump to the door leading to X-Ray either by jumping from spikes or with a very precise jump. Cross the room by Jumping atop the spikes. Taking enemy damage can be used to reduce some spike damage.

Freeze the Beetom and use it as a platform to climb the room without wall jumps. This can be done with well-timed Flatley jumps on top of the frozen Beetom, by turning around and spin jumping just as it unfreezes. This can be made easier (at the cost of some additional Beetom hits) with a pause-buffer method: Press pause, and begin a turn-around just before the pause hits; unequip Ice to immediately unfreeze the Beetom; unpause and press jump quickly after control resumes, but without buffering the input. For the top two jumps, it is possible to reduce the risk of damage by freezing the Beetom against the wall: in case of a failure due to an early (e.g. buffered) jump, the Beetom may stay stuck wiggling in the wall, and then it can be refrozen without needing to take damage to reposition it.

Leaving with upward momentum is possible in three ways: 1) Most easily, with a momentum-conserving morph against the ceiling through the transition, 2) With a momentum-conserving turnaround through the transition, or 3) Jumping specifically with a extra run speed $5.2 or $5.3 and aiming down through the transition. For the first two methods, avoid backing into the corner at the start of runway; instead press against it and turn around, to put Samus into a better position.

If there is a solid tile on the ceiling in the next room past the door frame, then the windows for the jump and morph are tighter. The momentum-conserving turnaround has a 3-frame window for the jump, and between a 1-frame or 4-frame for the turnaround (with later jumps giving a larger window for the turnaround); again the windows can be more narrow depending on what is required in the next room.

Dev note: Max extra run speed $4.4. Using the full runway, there is a 2-frame window for the jump, then a 1-frame or 2-frame window for the morph depending on the jump (with a last-frame jump giving a 2-frame morph window).

Back up against the wall of the single-tile ledge. Run forward, perform a single arm pump, and jump on the last possible frame. Aim down just before reaching the platform. The arm pump can be performed by pressing shot, or by pressing an angle button (but not releasing it until after the jump).

Enter the room with a Missile selected on auto-cancel, holding angle-up. Fire a Missile shot to kill the first Skree, then run right and immediately fire a beam shot to destroy the shot block. Run off the edge and down-grab onto the next platform. Run and jump directly up where the shot block used to be, moving quickly enough to dodge the Skree projectiles by going under them. Use a wall jump, HiJump, or a mid-air spring ball jump to make it up.

Wait for the global Sova to begin climbing the wall below the door. Have Reserves set to manual and couch jump up above the Sova as it turns the lip of the ledge. Before touching the Sova, pause, so that Samus will recieve a small damage boost followed by pause screen appearing. Set Reserves back to auto which will end Samus' i-frames enabling a second damage boost. Without Morphball, this requires a blind damage boost.

Position Samus into the bottom right corner, using i-frames to run and jump from the crumble blocks, and then wall jump to make it onto the ledge. If using a spike hit to gain i-frames, be sure to be holding forward (left) when landing, in order to get pushed back into the corner.

With Plasma and a pause abuse, it is possible to kill the Kago and exit G-mode while killing the Kago bugs and make it to the door with a small amount of Energy remaining. Shoot Plasma and quickly exit G-Mode, so that the bugs die immediately. Avoid having spent much time on the left side of the room, as the Fune fireballs will reduce the number of drops obtained.

It is possible to kill a Multiviola by the door and pause abuse to grab its Energy drop on G-mode exit. While luring the right Multiviola around the room, it is important to prevnt the Magdollites from spawning too many fireballs, otherwise the Multiviola won't give any drops. Either kill the middle Magdollite with a Super and stay away from the others when possible, or use Ice keep them frozen. Be careful not to touch any invisible flames that the Magdollites do spawn. It is also possible to do this with nothing; stand on the right platform while the Magdollite shoots to the right, then go to left edge of the runway to the right, pause abuse and exit G-mode while crouching and shooting upwards to kill and collect the flame drops.

Very quickly cross the room, collecting both items without falling into the lava. A Power Bomb in the middle of the room sets up the Sova drops and adds lag which makes the block item easier to collect with a Flatley jump. Farming the left sova and middle dragon increases the chances of getting enough health drops, but it may still not be possible with poor drop luck. Pause abuse can be useful for reaching the right side drops if the left side's luck was bad.

With wall jumps, ride the Tripper and wall jump twice above the middle spike, fall into the lava and jump back onto the Tripper and wall jump on the opposite side of the middle spike until it returns. Without wall jumps, jump into the lava in front of the Tripper, spin jump once to move quickly then again to land on the Tripper after the middle spike. With a very precise timing, it is possible to ride the second Tripper without touching the lava, otherwise, cross the second pit with the same method as the first. To cross the second pit, jump onto the Tripper as early as possible, then position Samus as far right as possible; this can be made easier with Moonwalk.

Enter the morph tunnel then exit G-mode. Shooting the shot block off screen can be done by jumping and shooting up or with Grapple or a Power Bomb. Getting positioned under the shot block can be done by walking into the camera scroll block and then walking against the right wall, jump to the left and walk a little more (about one more tile). This will also give some visibility of Samus. Without heat damage, it is recommended to jump up past the shot block and wait for it to respawn; with the block intact, Samus can't accidentally touch the lava.

Dev note: It is possible to jump over the left bridge pirate, but it is incredibly precise and not expected.

Run through the speed blocks then carefully cross the crumble bridge, as it will mostly be air. Alternatively, a speedball will prevent PLMs from overloading and Samus can roll over the bridge. Kill the pirate after the bridge before it places its invisible lasers, preventing Samus from getting through damageless. Samus can simply run to the right and fall through the bridge to safety below the pirate and kill it from below. It is also possible to perform one precise jump to cross most of the bridge and kill the pirate while blue.

Use a temporary blue chain to jump through the bomb blocks and land on the center of the ledge above.

Lure the Gamets to the top left door with Ice and Space Jump, Grapple, or HiJump. First lure the Gamets vertically using the Kamer platform and Ice, which is much easier with HiJump disabled. Then freeze them again after they separate and are high enough to align with the door. With HiJump and another jump assist, jump to the left of the Gamets as they thaw and refreeze them a bit more to the left so that they will be on screen when Samus is on the left ledge. It is possible with HiJump and Ice alone, but much trickier. Use the Gamets as a platform or perform a running jump from the Kamer platform to get up to the left door.

This will make it so that when Samus is below it, it will always swoop and go up slightly compared to the previous swoop.

Freeze a Mella at a precise distance below the door in order to crouch-jump up and clip through the door shell. The pixel window is larger and higher with Morph and an X-Ray stand-up, in which case a standing jump is used. It can help to moonwalk towards a Mella that has never been on screen, so that it starts swooping immediately as it first enters the screen. This will make it so that when Samus is below it, it will always swoop and go up slightly compared to the previous swoop. Once it is close to the right height, move away so it stops swooping, freeze it and quickly try the clip, if it doesn't work, quickly leave and try again.

Wait for the acid to lower then quickly roll part way forward to trigger the Metarees and return. Then go again without any difficulty. Killing any of the Gamets will prevent them from respawning. With Bombs, horizontally boost then IBJ above the acid while waiting for it. It is possible with Spring Ball alone, but it is easy to take damage; perform small jumps but hold jump before landing to prevent a small bounce in which Samus can't jump. On the return route, jump over the Gamets to let them pass instead of racing to get them off screen.

Despawn the gate in indirect G-mode then exit G-mode while under it to open the gate without a Super. This requires killing, freezing, dodging, or tanking the Rippers. Dodging the Rippers without Morph, requires crouching under the first two then jumping and aiming down over the next two; it also requires jumping over all three lower Rippers when most of the way across the room. Then exiting G-mode while on the right side of the gate tile as the first Ripper approaches, so it hits the gate while it's opening.

The room is a bit trickier to cross in direct G-mode because the Ripper cycle with the gate. Cross the room while killing, freezing, dodging, or tanking the Rippers.

The Zebbo needs to be 2 pixels higher than where it would be if Samus was standing. One setup is to peform a tiny hop just before the left Zebbo starts moving to the right then freeze it after it starts moving right. Get onto the runway and freeze the Zebbo again while maintaining a half-tile gap between it and the runway to extend it as much as possible. With more Energy, it is possible to morph on one of the medium-height pillars to align the Zebbo. With less Energy, it is possible to get the Zebbo into position by only freezing it once - after the small hop, jump towards the door and shoot downwards to freeze it in place.

Deal an exact amount of damage to a wall pirate to freeze it while breaking the bomb blocks with a power bomb without taking damage. Quickly move to the right side and walljump up to the right height to power bomb out the bomb blocks, double hitting the top wall pirate.

Deal an exact amount of damage to a wall pirate to freeze it while breaking the bomb blocks with a power bomb without taking damage. Wait briefly on the left side of the center platform, then jump and shoot 4 missiles at the top pirate. Walljump up the left wall such that the lower pirates are on screen long enough to jump accross to the left. Place a Bomb on the left wall to hit the top pirate when it jumps over, followed by a power bomb. Unmorph precisely below the middle pirate so both top pirates will jump back to the right, and begin charging Ice.

Climb up about half a screen. If Phantoon is dead, the last part of the climb should be done carefully to avoid triggering collision with the spikes: Do not press forward or turn-around except while X-Ray is active. For each X-ray stand-up, release the turn-around input quickly to make sure that it is not still held after X-Ray deactivates. Once Samus is high enough, unequip X-Ray, jump up (from either standing or crouch) to clip past the spikes, and land, taking a single spike hit. Then use the i-frames from the spike hit to run and jump to the left to make it to the door. Samus is high enough after the top of her arm cannon first becomes visible at the bottom of the screen; or up to 3 additional climbs can be performed after that point. In case of an accidental spike collision, it is possible to recover: Unless Samus climbed higher than needed, she will still be stuck in the wall, will take a single spike hit, and be able to continue climbing. With Grapple it is possible to swing on the Grapple blocks, avoiding all spike damage. Spike damage can also be avoided with Space Jump, by doing a stationary turn-around spin jump, which is very precise.

Double Spring Ball jump while artificially morphed and quickly unmorph and freeze the fish before landing on it. The required positioning of the fish is fairly precise; aim for it to be at the lowest point a few tiles from the right wall, or one tile from the right wall where Samus has more time to press against it. Down grabbing onto the fish makes this significantly easier. The fish should be frozen in one hit, this requires Plasma and Wave or a single Power Bomb hit and Plasma or Wave and Spazer. With Plasma, it is tricky to freeze the fish without killing it; avoid shooting it horizontally. The positioning of a Power Bomb, is fairly lenient, but will always hit the fish once if placed a couple tiles below the peak of a normal Spring Ball + HiJump.

Double Spring Ball jump while artificially morphed and quickly unmorph and freeze the fish before landing on it. The required positioning of the fish is fairly precise; aim for it to be at the lowest point a few tiles from the right wall, or one tile from the right wall where Samus has more time to press against it. Down grabbing onto the fish makes this significantly easier. The fish should be frozen in one hit, this requires Plasma and Wave or a single Power Bomb hit and Plasma or Wave and Spazer. With Plasma, it is tricky to freeze the fish without killing it; avoid shooting it horizontally. The positioning of a Power Bomb, is fairly lenient, but will always hit the fish once if placed a couple tiles below the peak of a normal Spring Ball + HiJump.

Samus needs to touch the item before PLMs are overloaded. This can be difficult because Power Bombs interact with the items, and there is a camera scroll block in the morph tunnel. If the Speed-locked item has already been collected on the other side of the room, this will be easier. Otherwise, Samus will need to touch the item before the Power Bomb finishes exploding. In this case, it is recommended to hold left on room entry, place a Power Bomb immediately as Samus hits the left wall, then hold left again until she lands on the pedestal.

Using the slow global crab to ascend the top section of the room requires the speed blocks to not be broken. Jump with either Springball or HiJump onto the global crab while it is climbing the section above the Speed locked item. Have Reserves set to manual and return them to auto after taking a deadly crab hit in order to gain two damage boosts. If the Speed blocks are broken, the global crab will not be able to reach this part of the room. If Morph is unavailable, then a down-grab must be done blind: buffer the down input through the reserve refill, then press forward immediately after taking damage.

Be sure not to get the first downward moving crab on screen until Samus is in position to quickly and accurately shoot and freeze it. This is much tighter with spring ball relative to HiJump. Performing a max height spring ball jump from the frozen crab can get Samus to the next ledge. Getting to the ledge with the fish is particularly precise. Either stand at the very edge of the platform and perform a very precise max heigh spring ball jump, or stand against the left wall and and perform a slightly less tight stationary lateral morph into spring ball jump.

In the other room, use 6 runway tiles to gain an extra run speed of exactly $1.D, with Speed Booster unequipped. Jump into a lateral mid-air morph and touch the door transition while descending close to the ground. Hold jump to do an uncontrolled bounce immediately after the transition. Pause as Samus passes under the first ceiling Grapple block. Equip Speed Booster and unequip Spring Ball, to get a spring fling. Pause again and re-equip Spring Ball to get a second spring fling. Continue holding jump to bounce on both Grapple platforms with uncontrolled bounces; Samus must bounce on the left edge of the first platform in order to just barely make the bounce on the right edge of the second platform. Perform one more spring fling, by unequipping Spring Ball as Samus begins to descend. Samus should make it into the nook below the right door; A Flatley jump into mid-air spring ball jump will get Samus up to the door.

Dev note: A comeInSpinning entrance condition is used to ensure it is possible to enter in the right position, even though technically Samus should enter morphed rather than spinning. With longer runway, a number of variations of this strat are possible: entering with a mockball (or controlled bounce) with speed at least $4.4, it is possible to bounce immediately on entry and do two spring flings to reach the second Grapple platform directly. with the same type of entry and speeds at least $5.4, it is possible do controlled bounces on both Grapple platforms, with no spring fling needed. FIXME: stopping at node 9 (below the top door) is also possible.

If HiJump or Spring Ball is available, use a Gravity jump from the top of the island; otherwise, use the higher ledge to the left, jump slightly early to avoid getting too much jump height (to avoid bonking the ceiling Grapple blocks), and quickly do a stationary lateral mid-air morph.

Run and jump up through the door using SpeedBooster in the room below. Bonk the door frame as you pass through the transition, to cancel your horizontal momentum. You need a vertical speed of exactly 7.8800 when passing through the transition, which requires the jump to be frame perfect. After the transition, as you reach the wall, begin holding right. Begin holding angle up at any time before approaching the door (and you can continue holding it until the end of the strat). As you approach the door (an 8-frame window), while holding angle up, release right for exactly one frame. This will put Samus into a pose aiming diagonally up and to the right. Immediately fire a shot to open the door (within the same 8-frame window); if successful, you will just barely clear the grapple block and pass through the door. Several things can cause you to bonk the grapple block: 1) entering the room with too much vertical speed, 2) not pressing against the wall as you come up, 3) releasing right for more than one frame, 4) releasing right too early. As an alternative to releasing right for one frame, you can instead press shot for one frame: if successful, Samus' pose will change to aiming diagonally without a shot being fired; if shot is pressed for more than one frame, then a shot will be fired horizontally, and the cooldown will prevent you from firing diagonally in time.

Jump with either Springball or HiJump onto a Sciser while it is climbing the right-most mountain. Have Reserves set to manual and return them to auto after taking a deadly crab hit in order to gain two damage boosts. This gains barely enough height to reach the ledge above.

Precise timing is needed to jump to the correct height: too high and Samus will bonk the Grapple block, too low and Samus will not make it onto the ledge. A Powamp may be in the path of the jump but can be destroyed with blue speed.

Entrance condition:

{
  "comeInRunning": {
    "speedBooster": true,

  }
}

Requires:

"canCrossRoomJumpIntoWater"
"canInsaneJump"

With Speed Booster equipped, run into the room using at least about 2 tiles of runway (at least $0.C extra run speed). If needed, perform two spring flings by pausing and unequipping Spring Ball, then pausing again and re-equipping it before bouncing on the first Grapple platform. Afterward, perform additional spring flings as needed to make it across the room, taking care to avoid the Powamp.

Enter the room morphed, either in a mockball on the ground or descending from a controlled bounce, with about 1 tile worth of speed (at least $0.9 extra run speed). Use Spring Ball to jump or do a controlled bounce after the transition. While descending and before bouncing on the first Grapple platform, perform two spring flings by pausing and unequipping Spring Ball, then pausing again and re-equipping it. Afterward, perform additional spring flings as needed to make it across the room, taking care to avoid the Powamp. Note that Samus must be fully morphed when entering the room (not in the middle of a morphing animation), or the spring flings will not work, assuming Speed Booster is not equipped.

Climb the bottom right wall of the room with Ice and HiJump while also luring a crab to the next platform to be used to ascend the next wall. The trickiest part of the climb is getting past the final overhang. This can be done with an underwater wall jump if the crab is low, a precise crouch jump and down grab if it is higher, or a flatley jump off of the crab if it is higher still. Two crabs makes it significantly easier to lure one to the top - simply let one go ahead of Samus. For a faster setup, one crab may be used by perform the final jump as it is unfreezing so it starts moving upward. Then go to the lower ground a bit to the right, jump and aim down to lower the camera to lure the crab. Note: The hardest part of this climb is the pixel precision when jumping around a ledge. Too many pixels: left is a fall, right you clip through the crab, low you miss the jump and fall, high is a bonk or crab clip.

Bounce onto the platform below the Speed blocks. Unmorph and continue holding up in order to break the Speed blocks while passing up through them. The top Speed blocks will respawn; to get on top of them, it can help to press against the wall (to discard blue speed) and then aim down to reduce Samus' hitbox. If available, using Grapple while aiming down can also help. Alternatively, if Samus breaks only the right column of Speed blocks, Samus can use the center left Speed block as a stepping stone. Be careful not to fall through the Speed blocks below as it will result in a softlock.

Needs near max horizontal speed coming from about 40 runway tiles in the adjacent room. Jump after the transition.

Stand on the edge of the sand and place a Bomb; unmorph (leaving Samus crouched), then press forward to enter the sand when the bomb flashes yellow for the second time. Once the Bomb puts Samus into a jumping pose where Samus is suspended mid-air slightly above the sand, press jump; then aim down precisely when the bomb begins to propel Samus upward. Move right to press against the wall before mid-air morphing (alternatively, a stationary lateral morph can work). There is a 2-frame window for when to enter the sand: if Samus enters the sand too early, she will sink slightly too far, resulting in not quite enough height to reach the tunnel; if Samus enters the sand too late, she will not get properly boosted by the Bomb explosion and will end up stuck in the sand. There is an 8-frame window for when to press jump, as it can be buffered during the period that the bomb begins interacting with Samus: if Samus jumps too early or late, she will get stuck in the sand. The timing for the aim-down press is frame-perfect: it must be pressed on the first frame that Samus begins being propelled upward by the bomb. if Samus aims down too early, she will get stuck in the sand; if Samus aims down too late, she will not get enough height to reach the tunnel. The timing for the jump is between 6 frames before or 1 frame after the down press. The amount of time that Samus holds forward after entering the sand is unimportant, as long as it is released before the aim-down.

  ]
}

Dev note: The timing window for when to press jump and when to aim-down is relative to the bomb explosion, independent of each other and independent of when Samus enters the sand. The timing for pressing forward (from a crouch) is 38 or 39 frames after laying the Bomb. The timing for the jump is between 51 and 58 frames after laying the Bomb. The timing for the aim-down press is 57 frames after laying the Bomb. It is also possible to stand by pressing up before entering the sand (in which case forward would be pressed 37 or 38 frames after laying the Bomb); this does not affect the size of the timing windows but introduces some more possibility for error, e.g. by the up input being eaten if Samus is still in the unmorphing animation, or by the forward input being not immediately processed if Samus is still in the standing animation.

Stand on the edge of the sand and place a Power Bomb; unmorph (leaving Samus crouched), then wait a moment before pressing forward to enter the sand. On the exact frame when the Power Bomb begins to propel Samus upward, press down, and press jump on the same frame or one frame later. Move right to press against the wall before mid-air morphing (alternatively, a stationary lateral morph can work). There is a 13-frame window for when to enter the sand: if Samus enters the sand too early, she will sink slightly too far, resulting in not quite enough height to reach the tunnel; if Samus enters the sand too late, she will not get properly boosted by the Power Bomb explosion and will end up stuck in the sand. The timing for the aim-down press is frame-perfect: it must be pressed on the first frame that Samus begins being propelled upward by the Power Bomb. if Samus aims down too early, she will get stuck in the sand; if Samus aims down too late, she will not get enough height to reach the tunnel. if Samus jumps too early or late, she will get stuck in the sand. The amount of time that Samus holds forward when entering the sand should be between 2 and 11 frames.

Dev note: The timing window for when to press jump and when to aim-down is relative to the Power Bomb explosion, independent of each other and independent of when Samus enters the sand. The timing for pressing forward (from a crouch) is between 27 and 39 frames after laying the Power Bomb. The timing for the jump is between 56 and 57 frames after laying the Power Bomb. The timing for the aim-down press is 56 frames after laying the Power Bomb. It is also possible to stand by pressing up before entering the sand (in which case forward would be pressed 28 or 40 frames after laying the Power Bomb); this does not affect the size of the timing windows but introduces some more possibility for error, e.g. by the up input being eaten if Samus is still in the unmorphing animation, or by the forward input being not immediately processed if Samus is still in the standing animation.

Lure a Puyo close to the sand to use for a Sand Grapple Boost. As it is close to entering the sand, land on the sand and crouch. Very quickly after crouching shoot the grapple and jump. As soon as the Puyo is killed aim down to escape the sand. If the timings don't work out just right, too much height is lost to the sand. Crouching in sand is also a high softlock risk.

Kill all of the enemies and leave drops uncollected so that the Zoas will not be in the way. Stand on the edge of the sand and place a Bomb or Power Bomb and wait briefly before entering the sand. Let the explosion push Samus up for a few frames before simultaneously jumping and aiming down. Then move left to down-grab onto the morph tunnel ledge. Jumping too early can lead to a softlock but jumping too late usually exits the sand safely.

Position as far left as possible, hanging over the ledge, and use X-Ray to turn around to the right. Perform a gravity jump into a spring ball jump. Immediately after the spring ball jump, unmorph to avoid bonking the wall and losing blue speed. Use a pause buffer to morph again without losing temporary blue: pause as early as possible, and hold angle and aim-down while the pause hits; during the black screen, hold only the down input, to buffer a morph; coming out of the pause, during the morphing animation roll from down to right, and then hold angle and unmorph to chain temporary blue.

Requires running a precise distance of 7 tiles with no open end in the adjacent room, to hit a peak of the speed vs height graph (at extra run speed $2.0 or $2.1). This needs a last-frame Space Jump in the previous room.

Stay out of the water, and by extension the sand, of the room by using the spikes as platforms. Morphing before landing on the spikes helps to be able to control the knockback. The final spike jump (which would be the most difficult) is avoided by doing a crouch jump into spring ball jump into IBJ to reach the left door. Perform the spring ball jump near max height. Place the first bomb between about 4 and 6 frames after the spring ball jump; ideally it should be just above the water line. Press pause between about 5 and 10 frames after placing the bomb, to disable Spring Ball (a 'spring fling', to reset fall speed). Place the second bomb soon after regaining control, while the game is fading back in. A spike hit in the center of the room can avoided by doing another spring ball jump into IBJ (also with a spring fling).

Dev note: The IBJ at the left side of the room can be done without a 'spring fling' but is far more precise: the first bomb must be placed exactly two frames before the spring ball jump, and the spring ball jump should be performed just before max height, during the 4-frame window between 2 and 5 frames before the last possible frame to jump (there are also 1-frame windows at 0 and 8 frames before the last frame).

Jump out of the sand to lure down mochtroids to freeze. It's recommended to bring a Mochtroid into the middle section of the room. Mochtroid damage is pretty hard to avoid, but can be. Mochtroid movement and freeze timing gets harder at the waterline.

Get a boost from a Bomb or Power Bomb while grappled to the bottom half of the turret above the door. Samus will enter a 'glitched grapple hanging' state where Samus' graphics will appear corrupted while swinging with Grapple. Slightly delay the down press to extend Grapple, to avoid getting caught on the corner of the floor. Swing down, and hold left while approaching the door to trigger the transition. Continue holding Grapple through the door transition to initiate a teleport in the next room. If Samus needs to be standing in the next room (e.g. for an X-Ray climb), then be sure to touch the ground before reaching the transition; this can be done by timing the Grapple extension early enough, or, if enough energy is available, by doing a small bounce before going through the transition. Samus can reach the transition at either horizontal position 20 or 21, depending on the specific timing and positioning of the swing. Pressing diagonal up-left just before the transition (to retracting Grapple slightly) can help more consistently reach it at position 21.

Get a boost from a Bomb or Power Bomb while grappled to the top half of the turret above the door. Without HiJump, this is most easy to do by positioning as far right as possible on the ledge and performing a stationary lateral morph. Lay the Power Bomb relatively low and continue moving right for about another half a tile. turn around left while morphed, then unmorph after Samus begins to descend, to reset Samus' fall speed; hold angle-up, and wait a moment after Samus is unmorphed before using Grapple (to wait until the bomb or Power Bomb is about to explode). Press and hold down soon after the Grapple attaches. Samus will enter a 'glitched grapple hanging' state where Samus' graphics will appear corrupted while swinging with Grapple. Swing down, and hold left while approaching the door to trigger the transition. Continue holding Grapple through the door transition to initiate a teleport in the next room. Samus should be able to stand in the next room (e.g. in case this is needed for an X-Ray climb). Samus can reach the transition at horizontal position 20, or at positions 19 or 21 by pressing up at a specific time just before reaching the transition.

Dev note: This is technically possible to do without a stationary lateral morph, but with much greater difficulty.

Get a boost from a Bomb or Power Bomb while grappled to the bottom half of the turret above the door. This can be done by standing at the very edge of the ledge, jumping up into a mid-air morph, laying a bomb or Power Bomb, unmorphing, then grappling diagonally. It can also be done with a crouch jump, without needing to be so close to the edge of the ledge. Samus will enter a 'glitched grapple hanging' state where Samus' graphics will appear corrupted while swinging with Grapple. After the Grapple attachment, hold diagonally down-left to swing directly into the door and through the transition. Continue holding Grapple through the door transition to initiate a teleport in the next room. Samus should be able to stand in the next room (e.g. in case this is needed for an X-Ray climb). Samus may trigger the transition at either horizontal position 20 or 21, depending on the specific timing and positioning of the swing. To reliably trigger it at position 21, press diagonally up-left just before the transition to retract Grapple slightly.

Get a boost from a Bomb or Power Bomb while grappled to the top half of the turret above the door.

Fire a charged Plasma shot, then use X-Ray repeatedly while the shot is in contact with Draygon, to wait out Draygon's i-frames. It is possible to one-cycle, which is easiest with a full beam, alternatively, it is possible to Morph under the swoop and two-cycle it.

Moonfall from the ledge just below the door, then weave between the floating platforms. It is possible to either perform the mid-air spark at high speed while falling, or to land and jump into a mid-air spark. Landing and jumping into a mid-air spark may be the easier method, especially if needing to leave in a specific position (top or bottom), but the shinecharge frames are very tight. It helps to get a good entry, by pressing down to gain the shinecharge as late as possible in the previous room; this will make Samus descend more during the crouching animation, to reach the ledge below quickly. It is recommended to initiate moonfall immediately, while still facing left, to avoid wasting time turning around. Alternatively, if activating the spark while falling at high speed, there are plenty of shinecharge frames available, but only a 2-frame window for activating the spark; if needing to leave in a specific position (top or bottom), it is frame-perfect; to leave in bottom position, break spin before the final turnaround, to adjust the alignment of Samus' vertical position, otherwise there is no frame that works.

Freeze the island Choot when it is at the far left of its second-highest swoop. Run right-to-left on it and perform a last-frame jump into a max-height spring ball jump. Getting the highest possible run speed requires starting from the right-most 87.5% of the last pixel (subpixel position at least $2000). Press pause at the same time as starting to run, or slightly earlier, and perform the mid-air morph quickly; timing the pause to hit as early as possible after morphing will maximize the time that Spring Ball is equipped, boosting Samus' horizontal speed and making it possible to clear the corner of the ceiling.

Dev note: There is at least a 3-frame window for freezing the Choot that works: two frames with the Choot in position ($2DE, $2F7), and one frame in position ($2E1, $2F9) It is possible to make the jump with one less frame of run speed; in this case Samus should start running from a few pixels further left, and a tighter mid-air morph may be required.

Run into the room, pressing pause immediately when entering. Jump into a mid-air spring ball jump to reach the ledge above. Perform the spring ball jump while still moving forward, in order to get a boost in jump height.

Roll off the above ledge and use both the vertical speed resets from first (un)equipping SpringBall and then by unmorphing in order to reach the door. Pause shortly after rolling off the ledge, after falling for 1 tile. The timing is very precise. A downback helps by shrinking Samus' hitbox.

Perform a 1-tap to gain blue speed with a significant amount of momentum. Run through the door, and jump near the end of the platform, crossing the room. If Samus gains enough height from the jump, it is possible unmorph mid-air to discard horizontal speed at the right side of the room, then pause to remorph (`canPauseRemorphTemporaryBlue`). Otherwise, a precisely timed unmorph is needed to avoid bonking the door and losing the blue state; at certain speeds, it may be necessary to briefly release jump in order to control the height for the unmorph.

The sand does not impede Samus in G-Mode. Carefully jump over the first two Evirs. Crouch against the pillar and wait a brief moment before jumping and down grabbing onto it. Lure the third Evir's projectile by jumping then crouch jump and down grab the second pillar. Getting onto the final pillar is the hardest pard, which requires a subpixel precise jump.

Dev note: This needs an extra run speed of at least $4.4. For speed $4.5, it helps to jump early and hold an aim-down pose. Speed $4.6 doesn't seem possible, as you end up too high to land without bonking the door, and too low to have time for a pause remorph? For speeds between $4.7 and $4.9, a pause remorph works. Speed $4.A is difficult but can be done with a last-frame jump, a momentum-conserving morph (ceiling mockball) while touching the second overhang, and a pause remorph. Speed $4.B doesn't seem to work as you can't avoid bonking the first overhang?

The Evir won't shoot unless Samus enters the sand falls. Getting to the transition tiles while standing before the projectile while suitless is very precise. From the sand, turnaround spinjump towards the right. Turn towards the sandfall about when you're level with the platform. Turn right and shoot as soon as you enter the sandfall. And try to land right next to the transition.

Use a 2-tap shortcharge and jump into the room with a last-frame jump, breaking the bomb block with blue speed, and making it all the way through the top door. Use angle to break spin, and do a momentum conserving turnaround either on the same frame or one frame later; this first turnaround should be done early enough that the turnaround is complete by the time Samus clears the two-tile passage in the middle of the room. Do a second momentum conserving turnaround must be done somewhat late, and by switching from holding left to holding right one frame later (a perfect 'boomerang'). Shoot open the door, and use a third momentum conserving turnaround on it as it opens.

Lower run speeds are generally better, as long as the extra run speed is at least $3.4. this gives up to a 7-frame window for the first turnaround, and typically a 4-frame window for the second turnaround if the first turnaround is done early enough. A perfect boomerang is always required for the second turnaround, regardless of where in the window it is done. It is recommended to buffer the spin break, by holding angle (up or down), jump, and forward through the transition, then switching from forward to backward, with at most 1 frame of neutral in between, while still holding jump and angle.

Bounce the snails around the room in order to destroy the sand blocks, opening up the runway. Without Gravity, this requires greater caution as the water will slow Samus down and increase the risk of taking damage from a snail. A snail can be made to bounce in 3 ways: shooting it off a wall or ceiling, kicking it on the ground, or touching it while it is already bouncing. Kicking a snail involves running or jumping into it with a non-zero amount of run speed, gained by dashing for at least one frame while in air physics. A snail can be kicked from any direction when in its initial (not angered) state or when it is stunned for a moment after being shot. While a snail is angered and is moving quickly, it can only safely be kicked from a certain side: from behind if on the ground, or head-on if on the ceiling (and not at all while on a wall). If Morph is unavailable, be careful not to let the snails go off-camera, and avoid getting stuck in two-tile-high spaces. If a snail is on the ground and still on camera, it can be forced to move toward Samus again by shooting it; let it wrap around the right side of the room onto the ceiling, where it can be shot to cause it to fall and continue destroying sand blocks.

{
  "notable": "Tricky Speedy Jump (Left to Right)"
}
"canSuitlessMaridia"
"canTrickyDashJump"
"canInsaneJump"

Dev note: Speeds above $4.4 cause Samus to bonk the ceiling, losing all vertical speed, or the overhang, losing all horizontal speed; there is a significant amount of vertical speed to lose, even though it may not appear that way because of how the sandfalls push Samus down. Speeds in the range from $4.0 - $4.3 give a spike in jump speed, resulting in a ceiling bonk even earlier. Speeds below $4.0 are not close to enough to make it across.

In the other room, gain run speed using at least 36 tiles (extra run speed at least $6.4), and Space Jump low through the door. Land on the block just past the last Evir.

Entrance condition:

{
  "comeInSpaceJumping": {
    "speedBooster": true,
    "minTiles": 36
  }

Run into the room with an exact amount of speed, by using 7.5 tiles of runway or up to 4 pixels more (getting extra run speed exactly $2.3). After entering the room, jump from the last tile or two of runway, perform a lateral mid-air morph, and land on the pillar just past the last Evir.

Entrance condition:

Dev note: A speed of $2.2 can also work but it requires a last-frame jump and a tight lateral mid-air morph.

Enter on the right side of the transition and move left to avoid damage.

Dev note: Entering from a non-sand room makes the suitless+hijumpless dodge only possible with a walljump. Entering through the Toilet does not affect this dodge strat much.

Perform multiple stationary lateral mid-air morphs, while avoiding the Evir projectiles, to cross the room. It is necessary to start the jumps from the far side of the platforms in order to gain more horizontal momentum before entering the sand falls. Falling into the sand will often result in a soft lock.

Use the projectile from a fully submerged Evir to boost Samus into the sandfall, providing just enough height to make the first and hardest jump. Time the projectile to hit Samus when at the maximum height from a jump. The hit must be on the right side of Samus and with no inputs held, but also hold forward during the damage knockback to move through the sandfall. Getting a good jump while on the right side of the next floating block can get Samus to the leftmost block. With a clean jump off of the sand, Samus can then get onto the final vertical pillar.

Avoid the Baby Metroid with no items at all. Jump over it many times in order to clear a path through the seaweed. With a counter clockwise setup, stand as close to the transition as possible while allowing the Baby to circle Samus. Then jump towards the transition and touch it with a walljump check. A clockwise setup is more difficult to clear the seaweed, but can jump directly into the transition.

Dev note: FIXME: Add a Baby Skip with a flash suit. Note, however, it will only pair with rooms that have an entrance condition where Samus is sparking. In order to have it be properly implemented, all horizontal doors will need to have a shinespark entrance condition added.

Enter through the far left side of the door. Wait for the top hopper to move right to start running. Run under the right Hopper and jump over the left Hopper to avoid all damage. Jump when Samus reaches the leftmost lump in the ground to avoid the left hopper. It helps to keep the camera scrolled to the right.

Try to scroll the camera to the right to keep the left Hopper off-camera for longer. Wait for the top hopper to move right to start running.
